The most common OWCP forms you'll encounter — with plain-language explanations of what each one does, when you'll need it, and who completes it.
OWCP uses specific forms for each phase of a federal workers' compensation claim — CA-1 (traumatic injury notice), CA-2 (occupational disease), CA-7 (wage-loss compensation), CA-16 (treatment authorization), CA-17 (duty status report), and CA-20 (attending physician's report). Below, the most common forms are explained in plain language — what each does, when you'll need it, and who completes it — followed by the complete directory of all DOL OWCP forms with links to the official PDFs.

Note: Official OWCP forms are published and maintained by the U.S. Department of Labor. Always verify you're using the current version on the DOL OWCP forms page. The guides below are NuThera's plain-language companions — not replacements for the official forms.
File a CA-1 for a traumatic injury — an event, accident, or incident that occurred during a single workday.
File a CA-2 for an occupational disease or illness that developed over time — repetitive strain, chronic conditions, exposure-related illness.
File a CA-2a when a previously accepted work injury flares up again after you've returned to work — without a new workplace incident.
The form for claiming wage-loss compensation when you can't work — used after Continuation of Pay ends (traumatic injuries) or from the start for occupational disease claims.
Authorizes initial medical evaluation and treatment for a work-related injury within the first 60 days of injury.
